So we are looking for the price per lb....
price / lb : so be sure and put the price divided by the lbs

10.50 / (3 1/3) = 10.50 / (10/3) = 10.50 * 3/10 = 31.5/10 = 3.15 per lb

6.25 / (2 1/2) = 6.25 / (5/2) = 6.25 * 2/5 = 12.5/5 = 2.50 per lb

so the better deal is the 2 1/2 lb turkey <==

** keep in mind, when dividing fractions, flip what u r dividing by, then multiply

Which is the best estimate for this<br><br> 4/5% of 192
slavikrds [6]
When you are looking for a fraction, it is best to convert this into a percentage, which in this case, is 80%. Following on from this, you will have to round the number up, which in this case, will be to 200- however, depending on the number, this could be different. From this, you then have to find 80% of 200. From this, you then have to divide 200 by 10, giving you 20, and then multiply this by 8, to get 160, and this is a good estimate for 4/5 of 192. Hope this helps you <span />

lions [1.4K]
The answer is 7 < x < 13.

5 < x - 2 < 11
Add 2 in all sections:
5 + 2 < x - 2 + 2 < 11 + 2
7 < x < 13
